Cant' login (demo:demo) in wildfly distribution

[Patrick Werner]

I just tried to run the prepackaged camunda wildfly server.

d/l -> unzip -> startserver.sh

I can see the welcome page. If i try to login in cockpit or taskmanager  with demo demo i get a Unauthorized :

Login is required to access the resource message.
In the logfile (http://pastebin.com/gbJ53Eac) i can see the following errors:

• [stderr] (ServerService Thread Pool -- 54) ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider com.sun.script.javascript.RhinoScriptEngineFactory not found

what am i missing here?

Hi Patrick,

Just try to restart the server again. It seems that it is a Wildfly bug,
see [1] and [2].

Cheers,
Christian

Hi Christian,

i (of course) tried several restarts. Still not working.

The problem might still exist in 8.2.0. There was a fix in March this year, see [1].
This fix will be part of 8.2.1 if it will ever be released.
But as it simply is a fix in an module.xml file, you could add the same line to your unzipped Wildfly version.
Filename is modules/system/layers/base/sun/jdk/main/module.xml.

Hi Patrick,

Did you try to to clean your browser cache / use anonymous mode in your browser logging in?

Cheers,

Christian

I tried to fix the module.xml and cleared all caches.

The problem is related to Java8 i think.

So i tried to use wildfly9 - without any success, run into the same issue as mentioned here:

https://app.camunda.com/jira/browse/CAM-3709

I then tried to compile the wildfly9+ fork:

https://github.com/langfr/camunda-bpm-platform/tree/wildfly9+

Without any success:

[ERROR] /Users/patrickwerner/Downloads/camunda-bpm-platform-wildfly9-/engine/src/main/java/org/camunda/bpm/engine/impl/cmmn/handler/HumanTaskItemHandler.java:[202,37] cannot find symbol
  symbol:   method getCamundaFollowUpDate()
  location: variable definition of type org.camunda.bpm.model.cmmn.instance.HumanTask

Im using maven 3.3.3 with JDK  1.8.0_51.

Has anyone managed to get camunda working with wildfly9 / JDK8 ?

I think @frank hast this combination working. What am i doing wrong whilst compiling your fork?

[Frank Langelage]

I think branch wildfly9+ never build successful, there I started to make the number of threads configurable as it was before, using JBoss's threads module bus got stuck somewhere.
Branch wildfly9 unfortunately shows the same problem. Don't know why and since when. Do not have time available right now to spend on this problem.

You might take the master branch and build this: mvn clean; mvn install -Pdistro-serverless -Pdistro-wildfly9.
This is based on the current Camunda-BPM 7.4.0-SNAPSHOT as of last Friday, using WildFly 9.0.1. I regularly update this branch with the latest commits from camunda/master.
I just cloned this branch and build it and tried it. It works for me.

This I tried only tried to compile and run it with JDK 7.
But I'm using this camunda-bpm module wildfly9 also together with WildFly 10 Beta1 (WF 10 requires Java 8).
